' l Patented am.r 15, 193e Gamme mama QF.; WTB-teem 'senese wenn@ ,Fee Meme entre# soies f Application 'filed November This invention relates to machines for mak-k ing dental'rolls, whereby a given length of a. certain width-of absorbent. cotton is rolled over itself tightly and properly impregnated 5 and `dried,rso asto form a ro'und stick that may be cut into various lengths, for use in vdental toilet, surgery and like purposes.

fThe principal object of this invention is to properly automatically roll VandY impregnate 51.0 the priedetermined layers of absorbent cotton,

inthe form A1`?ecpuired `by the product. 'Another object is to automatically convey the impregnated and rolled product through' a drying" chamber andv automatically deliver the saine into alpicking container.

- These objects and other advantages will be shown in the hereinspecication'and in the accompanying drawings, in whichzl Figure 1 isa general view, in side elevation of' the invention. a, .Y A Y,

The relative ,motionv of each pair f of rollers 6 and 7 and" 9 and 10, istr'ans f mitted through` a pinion 11 integral with Pthe roller 7 anda pinion 12 integral with the roller10,`by a gearlf havingan intermit-.- S9

The-" earl?) is, uitably mounted upon a shaft 15 Therolling mechanism unit 2, consists of `an endless belt 17 travelling in the direction indicated by` the-arrow 18, upon which the layery 19 has been partly pushed (see Figure 20, projecting across and beyondthe layer 90 19 andacross the width of the b'elt17, onl the forwardedge of the said layer 19. vflhe'belt 17 conveys the 'layer `19'ui1der the edge of a stationary vplatform 21, to which the edge 'of' the layer 19,'bearing'the` rod v20, adheres-'suf- .95

ficiently tofcause its'unrolling around the saidV4 rod 20, as it advances in contact withthe belt 17.v The platform'21is preferably made of f wood'and is fastened or secured under asu-itable rigid' plate 22' and-canbe easily madeiadi90 justable by means of suitable jack screws 23.

Therefore, the platform 21 can conveniently i be adjusted to continuously be in suitable contact for rolling of the layers 19.

The impreg;natir'ig` unit 3, consists of a roller 2a, covered preferably with a substantial layer of linen 25, or otliersuitable absorbent material, revolvingiy bathing` in a bath of a liquid suitable preferably a. mixtureof flour and water conveniently placed into a receptacle 26 having a suitable funnel-shaped filler 27. The belt l? is main aiiied closely in contact with the layer 25 of ine roller 24, by means of a suitable idler 29Y acting as a tiglitener for the saine. The liquid derosited upon the belt i7, will carry s me pic" V the. absorbent cotton layer i9, and said piel;- ings are preferably talren ofi the said belt l? by means of a suitable idling roller carrying l l J.

Units 2 and 3 are actuated preferably by a d ouble pulley 34 suitably geared to Y rear roller 35, pullinglthe belt l? horizontally, on either end* of which are mounted sprockets 36, from which a suitable endless chain 37 is driven. A, conveyant 'tightener 38 is mounted across theV framework 33, for maintaining a taut drive ofthe endless cha... ,37.

l The dryingchamber l consists of a suitable long,` joven having upper and lower com-partments 39 and 4l() respectively. @peni by the comb 3l, which can easily be cleaned.

Y are made into the walls of this chamber 4 Tor the free passage of the chain 87 carryingv the rolled-layers 19, which noY-.vmay be Ycalled rolls lll. 'A supp y of hot air is furnished through the lower compartment 4,0 that'circulates through theA entire length thereof'a'n'd similarly through the comuartment 39.

Mounted'at predetermined intervals upon the chain 37., are hooks 42 (seeFigure 7). The hooks l2 which are of S shape are mountd on a base 23, each of said hooks being 1 suitably secured at intervals on the chain 37.

and are'so constructed'that tney carryl the rods 20, while ascending obliquely,liold the same while going horizontally in the saine direction, similarly when descending` vertically .andV moving back horizontally, until they descend obliquely, when the rods 2O fall out of them, when they have reached a point above the chute 43, which directs the said rods 2O carrying the rolls al into the receptacle The platform 2l is preferably grooved under, as shown in dotted lines in Figure n, for

several purposes. Firstz-lto prevent the positing' a xwiiereby said layers will be impregnated and distribute evenly the impregnating deposit adhering from the enrolling layers 19. rl`hird r-to `give a better friction bearing to the unrolling layers 19.
